Logos don’t bother me; am using the dark theme so maybe afre might have a point. Regardless, you have to give credit with credit’s due and I don’t see anything wrong with the logos. Doesn’t take away, at all, from the effectiveness of the G’MIC plugin period. Yes; it’s a matter of taste but so is choosing to use G’MIC.
Keep up the great work, David. Personally am thankful for the entities that support your endeavors.
